Improved folding bed-bottom



UNITED STATES PATENT OEEICE.

IMPROVED FOLDING BED-BOTTOM.

Specification forming part of Letters Patent No,l 42, |08, dated March29, 1864.

To all whom it may concern:

Be it known that I, F. G. PAYNE, of the city, county, and State of NewYork, have invented a new and Improved Folding Bed-Bottom; and I dohereby declare that the following is a full, clear, and exactdescription of the same, reference being had to the accompanyingdrawings, making a part of this specification, in which- Figure] is aside view of my invention Fig. 2, a longitudinal central section of thesame, taken through the center.

Similar letters of reference indicate corresponding parts in thetwofigures.

This invention relates to an improvement in the construction orarrangement of the joint ot' the bed-bottom, whereby the same, withmattresses attached, may be compaetly folded withoutinjuring themattress, as is the case where an ordinary joint is employed, inconsequence of the mattress being bent with a quick curve, which creasesthe mattress and soon causes it to become chafed and worn.

My invention consists in constructing the joint which connects the twoparts of the bedbottom together with a central bar, arranged in such amanner as to admit of the mattress being bent over with a gradual curve,and to cause the mattress to be compactly folded without the liabilityof injuring the same.

To enable those skilledin the art to fully understand and construct myinvention, I will proceed to describe it.

A A represent two rectangular frames, tothe upper parts of which amattress, B, is secured by nails a or other proper means.

O represents springs, which are connected to the under side ofthemattress and to slats b at the bottoms of the frames A A. (See Fig. 2.)

The frames A A are of equal dimensions,

and they are connected together by a joint constructed and arranged asfollows:

To each side of each frame A, at the inner surfaces thereof, there aresecured metal plates c, which are parallel with the ends of the frames,(see Fig. 2,) and these plates o at each side of the frames areconnected by metal plates d, the ends of the latter having pivots cpassing through them into the plates c.

When the two frames A A are adjusted in a horizontal position for use,the lower parts of the sides of the frames A A are in contact, as shownat eX in both figures; but the upper parts of said sides above e arerecessed or notched, so as to leave a Vshaped space between them, inwhich V-shaped blocks D are fittedv These V-shaped blocks Dare securedby screws or bolts f to the plates d, and it will be seen that they, inconnection with theplates d, form an open joint and admit of a mattressB of a requisite thickness being used, and one which may be turned overand folded compactly together, as shown in red in Fig. 1, withoutcreasing the mattress or subjectin git to an undue abrasion and wear.The joint also is a strong and durable one, and renders the bed-bottomstiff and rm.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is-

A folding bed-bottom provided with a joint'
